Description
Technical field
This utility model belongs to new-energy automobile field, is specifically related to a kind of mobile container battery compartment charge-discharge system based on common DC bus.
Background technology
Mobile container battery compartment needs polylith battery series-parallel connection could export corresponding electric current and voltage, and the battery management system (BMS) of each battery is required for connecting Controller Area Network BUS (CAN) and communicates with DC/DC module, mobile charging storehouse typically uses the mode that each battery is all directly connected to DC/DC module at present, this kind of connected mode causes wiring complex, and once break down, being difficult to be accurately positioned, this causes an a lot of difficult problem just to reality application.
Summary of the invention
For solving the problems referred to above, it is an object of the invention to provide a kind of mobile container battery compartment charge-discharge system based on common DC bus, to make up the deficiencies in the prior art.
The input of each battery of mobile container battery compartment is all directly connected with common DC bus with out-put supply line, and the CAN of set of cells also accesses common DC bus, drastically increases the reliability and maintainability of system.
For reaching above-mentioned purpose, the concrete technical scheme that this utility model is taked is:
A kind of mobile container battery compartment charge-discharge system based on common DC bus, it is characterised in that this system is entirely encapsulated in a moving containers, and system external is charged with external power supply or is connected with electric automobile discharging；Being provided with the battery compartment of multiple battery inside this charge-discharge system, each battery compartment is connected with two-way DC/DC module by common DC bus, and the BMS module of each battery compartment is connected with two-way DC/DC module by CAN；When said system is charged, external power supply communicates with the BMS module of each battery compartment again to two-way DC/DC module for power supply, two-way DC/DC module, and then completes charging by common DC bus to battery；During said system electric discharge, two-way DC/DC module communicates with the BMS module within new-energy automobile, and collects output by common DC bus, is finally completed the charging process to outside new-energy automobile.
Positive and negative two input lines of described battery are directly accessed common DC bus, and are consulted to provide corresponding electric current and voltage by above-mentioned two-way DC/DC module and BMS module.
The CAN of described battery is connected with above-mentioned two-way DC/DC module communication by common DC bus.
Described external power supply is external direct current power supply.
Advantage of the present utility model: the charge-discharge system that this utility model provides utilizes multiple batteries of common DC bus and container battery compartment to be directly connected to respectively, and be joined directly together with common DC bus by two-way DC/DC module, battery with external power supply and new-energy automobile is indirectly connected to the most respectively, has been finally completed power supply and electric discharge.The most traditional connection in series-parallel Routing models is changed to common DC bus pattern by this utility model, it is simple to the plug of battery and replacing, it is possible to need to adjust electric current, voltage easily according to system, it is achieved concrete flexible layout wiring, is easy in actual applications promote.
Accompanying drawing explanation
Fig. 1 is this utility model structural principle block diagram.
Detailed description of the invention
Below by way of specific embodiment and combine accompanying drawing and this utility model is explained further and illustrates.
As it is shown in figure 1, this utility model is entirely encapsulated in a moving containers, system external is charged with external power supply or is connected with electric automobile discharging, and thick line represents that common DC bus, fine rule represent CAN；Being provided with the battery compartment of multiple battery inside the present embodiment, each battery compartment is connected with two-way DC/DC module by common DC bus, and the BMS module of each battery compartment is connected with two-way DC/DC module by CAN；Positive and negative two input lines of described battery are directly accessed dc bus, and are consulted to provide corresponding electric current and voltage by described DC/DC module and BMS system；The CAN of described battery is connected with DC/DC module communication by dc bus.
During said system charging, external direct current power supply communicates with the BMS module of each battery compartment again to two-way DC/DC module for power supply, two-way DC/DC module, and then completes charging by common DC bus to battery；During said system electric discharge, two-way DC/DC module communicates with the BMS module within new-energy automobile, and collects output by common DC bus, is finally completed the charging process to outside new-energy automobile.
Said system controls the contact with common DC bus by two-way DC/DC module, and each battery individually can be separated from dc bus and not affect system, and this also makes it easy to location and carries out failture evacuation.
Above content is to combine concrete preferred implementation further detailed description of the utility model, it is impossible to assert that of the present utility model being embodied as is confined to these explanations.For this utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, it is also possible to make some simple deductions or replacement, all should be considered as belonging to protection domain of the present utility model.
